WebGLRenderingContext: bindTexture() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The WebGLRenderingContext.bindTexture() method of the WebGL API binds a given WebGLTexture to a target (binding point).

Syntax

js
bindTexture(target, texture)

Parameters

target

A GLenum specifying the binding point (target). Possible values:

  • gl.TEXTURE_2D: A two-dimensional texture.
  • gl.TEXTURE_CUBE_MAP: A cube-mapped texture. When using a WebGL 2 context, the following values are available additionally:
    • gl.TEXTURE_3D: A three-dimensional texture.
    • gl.TEXTURE_2D_ARRAY: A two-dimensional array texture.
texture

A WebGLTexture object to bind.

Return value

None (undefined).

Exceptions

A gl.INVALID_ENUM error is thrown if target is not gl.TEXTURE_2D, gl.TEXTURE_CUBE_MAP, gl.TEXTURE_3D, or gl.TEXTURE_2D_ARRAY.

Examples

Binding a texture

js
const canvas = document.getElementById("canvas");
const gl = canvas.getContext("webgl");
const texture = gl.createTexture();

gl.bindTexture(gl.TEXTURE_2D, texture);

Getting current bindings

To check the current texture binding, query the gl.TEXTURE_BINDING_2D or gl.TEXTURE_BINDING_CUBE_MAP constants.

js
gl.getParameter(gl.TEXTURE_BINDING_2D);
